The invention discloses a high-gas-velocity dish-shaped negative electrode applicable to a wet type electrostatic defogger. The high-gas-velocity dish-shaped negative electrode comprises a support assembly, a rigid support (2) and dish-shaped discharging plates (3), wherein the support assembly comprises a fixing plate (1-3), an adjusting plate (1-5), three adjusting screw rods (1-4) and a fixing bolt (1-1); the fixing plate (1-3) and the adjusting plate (1-5) are equilateral triangular steel plates; the center of the upper fixing plate (1-3) is connected with the fixing bolt (1-1); the upper fixing plate (1-3) and the lower adjusting plate (1-5) are connected through an adjusting screw rod (1-6) at each corner; the center of the lower adjusting plate (1-5) is fixedly connected with the rigid support (2); the dish-shaped discharging plates (3), which are parallel to each other, are vertically fixed on a middle defogging section of the rigid support (2). The high-gas-velocity dish-shaped negative electrode has the advantages of being capable of discharging evenly, good in corrosion resistance and especially applicable to operation under the high gas velocity.
